It is worth noting that in the cheaper MTK chips, a number of modules responsible for cryptography at the hardware level are not implemented. If Secure Startup mode is disabled in the OS settings, the default password (default_password) is used by the system, which is the standard behavior of the Android OS. If the memory of an MTK device is encrypted, the extracted physical dump content will be encrypted as well, and the user will have to enter or identify the password in order to decrypt the data. Encryption is performed using hardware support. In MTK-based devices a security mechanism known as Full Disk Encryption is generally used.

To support devices that do not work with the standard DA file, a third-party DA file can be uploaded in Oxygen Forensic Detective.Īndroid OS offers complete encryption of the device’s memory, and is enabled. This operation does not change the device firmware and, therefore, is safe for its operation and data preservation.ĭA mode provides a higher-level device interacting API and offers commands for reading the physical dump of the device.

In order to read the memory dump, a special loader (DA file) is loaded into RAM, automatically putting the MTK device in Download Agent (DA) mode. In BROM mode, basic information about the hardware of the MTK device under investigation can be acquired. Some devices do not work with the standard driver and require a special driver from the manufacturer. Otherwise, the user will have to reinstall the driver within the system or find the correct driver for this device and repeat the process. If the MTK driver is installed correctly, the extraction process will continue. If the response is not received from the PC within 1 second, the device turns off and switches back to USB charging mode.įor optimal functionality in this mode, we recommend installing a driver to the system, which is included in the product. This mode allows information exchange with the MTK device over the proprietary protocol. The device must be put into BOOT ROM (BROM) mode before starting the reading.

Oxygen Forensic Detective currently supports more than 100 modifications of MTK chipsets. The extraction method is based on a low-level proprietary protocol designed for firmware updates and recovery of MTK-based devices, which permits extraction from password-locked devices. Recognizing this, Oxygen Forensic Detective offers data extraction for Android devices based on MTK chipsets. is one of the largest smartphone chipmakers in the world.
